EDGE JOINT & TIER WELDS for ELECTRON BEAM WELDING

Edge joints are generally used with sheet materials such as hermetically sealed cans, etc.

This type of joint is especially useful in areas where the parts are used, disassembled, refurbished, and resealed by welding.

Figure 16a and Figure 16b show two types of edge joints.

This weld requires a low power, defocused electron beam. High welding speeds are possible.

Metal to metal contact provided by good quality copper chill bars is essential to control weld puddle contour.

Components containing several stacked weld joints, usually lap joints, can be simultaneously welded as in any "tier".

This is unique to the electron beam welding process, using the key-hole welding mode.

This joint design may be limited by access to NDT techniques
